Cisco 861 - Firewall configuration not available with CCP

Setup new Cisco 861 and working well for a new BTNet line for the customer. Changed the firewall using CCP from Zone to Classic Firewall. Worked great all day and configured what I needed to do.

Now, with CCP (version 2.6) have the following message:-

** Cisco CP has detected that the router is configured with either legacy and Zone Policy Firewall (ZPF) or Legacy firewall. If you want to use Cisco CP to configure an zone-based firewall, you must first delete the Legacy configuration. **

Can anyone help, please?

The config of the router is below with details customer details changed:-

I realise what the message says. I can configure the firewall using CLI when I need to. However I have colleagues that find it easier to use CCP.

My point is, is that I could configure the classic firewall using CCP but now I cannot. The message says to delete classic entries (which is all of them). I could start to take a more aggressive approach by deleting using the CLI all entries relating to the firewall (classic or zone) which would not only risk me cutting myself off on a bank holiday weekend, but also risks disrupting the customer.

The assistance I require (only being a CCENT n all) is to help identify where the zone firewall remnants are in the config that need removing.

I could of course start the config again, but would like to avoid any disruption.
